IMPROVEMENT IN STITCH-RIPPERS.

Specification forming part of Letters Patent No. 164,336, dated J une 8,1875; application tiled May 4, 1875.

To all whom it may concern:

Be it known that I, GEO. ST. GEORGE, Jr., of Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a certain newand useful Stitch-Ripper; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the lart to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.l

Figure l is a side view, also showing` method of attaching to table.Fig. 2 is a partial plan view. Fig. 3 is a transverse sectional view ofthe cone. Fig. 4 is a detailed sectional view.

My invention relates to a method of separating or ripping seams sewedeither by machine or hand. It consists in a cone and handle, which areso constructed that the cone will be stiifened, cannot be opened, and achannel is formed for the bar which carries the knife or blade. It alsoconsists in rendering the knife adjustable for various kinds of work. Italso consists in a guard for pre` venting cutting of the fabric.

Referring to the drawings, A represents a cone or conical shaped stock,which is connected to a holder or handle,B, and has an opening, O, inthe length thereof. In forming the cone A, a piece of metal or materialis bent into shape, and the ends thereof continued inwardly toward thecenter of the cone, so as to form tongues b b, and said tongues aredepressed laterally near the surface of the cone, to form a channel, a.The handle B is pointed or L-shaped at one end to correspond to the coneA, and a slit, d, is formed in said handle in the longitudinal directionthereof. D represents a knife or blade, which is iitted to a holder, K,whose shank passes through the opening C, and is connected to afeed-bar, which is fitted in the channel a, and has au adjustable.sliding motion therein, and also plays in a slot or channel in thehandle, which latter carries the mechanism by which the adjustingmotions of the bar and knife are imparted. L represents lips, whichproject from the sides of the knife, and act as guards to preventcutting of the fabric.

It will be seen that when the parts are in position the walls or sidesof the slit d of the handle embrace tongues b and channel a, and theythus serve to stiften the cone, prevent opening thereof, and strengthenthe channel a, which forms a way for the feed-bar. The knife may bereadily moved nearer to or farther from the point of the cone, to meetthe requirements of various kinds of work, as will be hereinafterstated.

The method of operating my invention is as follows: In closed seams orhems, the point of the cone is inserted in the hem, bringing the threaddirectlyin line with the knife. The cloth being then pulled over thecone, the seam partially separates, and the thread, striking the knife,is cut, the knife being iirst set in the cone according to the size ofthe seam. In case of open seams, or two pieces of cloth sewed together,the knife is set back to the base of the cone; the cloth is then pulledbackward and slightly downward, as before.

The advantage of this particular device over any heretofore in use ornow used consists in partially separating the edges of the seams bymeans of the cone, and then bringing the thread continuously tothe knife5 also, in the adjusting of the knife to diiierent-sized seams; also, inthe guard provided for preventing the knife from cutting the cloth.

I claim as my inventionl. The cone A, formed with the opening C andchannel a, in combination with the slit handle B, substantially as andfor the purpose set forth. v

2. The combination, with the cone, of the knife D, having au adjustableor sliding movement on the cone, substantially as and for the purposeset forth.

3. The guard-lips L, in combination with the knife D, substantially asand for the pur-- pose set forth.
